What is this for? (PIC)

[DPow]

My uncle was changing my fuel pump and broke the vacuum hose off of this canister looking thing. He said i didnt need it and my car runs fine without it. What is it for and DO i need it?

Emissions equipment. For inspections you're supposed to have those items but there are ways around it.

[DPow]

We don't do inspections in Minnesota so if its not hooked up its not gonna kill my car?

Its a charcoal canister. There is a diy on how to delete that and the box above it.

[deevergote]

It basically filters fuel vapors from your gas tank.

I would replace it. Don't delete your emissions equipment. There is a reason why certain states have stringent emissions laws... because careless people made a mess of the air in those states. Your state has clean air. Do your part to keep it that way. It's a $5 part at the junkyard, I assure you.

Isn't it needed to run on vapors anyway? I thought it re-liquefies them.

The charcoal canister absorbs fuel vapors while the car is not running. Once the engine is running, those vapors go into the combustion chamber to be burned off.

Empty gas tank is gas and air that fills the rest of the tank. When you fill it up, air is taken out of the empty space and is filled by gas instead. When you seal your gas tank with the cap, it's shut off. No air is going in or coming out.


When you take off the cap, the hissing is just air being sucked into the gas tank.


Kinda like when you take a soda bottle and suck out the air. When you take your mouth off of it, air flows right back in and the bottle returns to it's original shape.
